Examples

In this example, we create an Input Table and then print the result of a call to hasAttribute().

import io.deephaven.engine.table.impl.util.AppendOnlyArrayBackedInputTable
import io.deephaven.engine.table.AttributeMap

source = newTable(
    doubleCol("Doubles", 3.1, 5.45, -1.0),
    stringCol("Strings", "Creating", "New", "Tables")
)

result = AppendOnlyArrayBackedInputTable.make(source)

println result.hasAttribute("AddOnly")
